LOCK.

Application filed December 8, 1817. Serial No. 206,322.

To all fio/Loan t may con-cern Be it known that l, HENRY G. VofiGHT, of New Britain, county of Hartford, Sta-te ot Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact dev scription.

This invention relates to locks, and more particularly to a cylinder lock designed to be mounted upon the rear face of a sheet metal locker door and constructed to prevent the knob upon the door from being turned to unlock the locker door .by withdrawing the bolts upon the door from their infotracted position. llowever, it will be apparent thatvmy invention is capable of other uses.

The principal object ot the invention is to provide means for holding :i locker knob in its locked position, so that an unauthorized person cannot turn the knob to open the locker. lilore particularly the principal object is to provide a cylinder lock which may be readily applied to the rear face of the door of a sheet met-al locker, the lock being` positioned adjacent the swinging bolts of the 'door to hold the bolts in their locked posi tion.

A further object of my invention is to provide means by which a plurality of bolts mounted upon the inner .tace of the door may be simultaneously operated when the knob on the outer tace of the door is turned.

To these and other ends, the invention consists in the novel :tea-tures and combinations of parts to be hereinafter described and claimed.

ln the accompanying drawing:

Fig. 1 is a fragmentary viront elevation of a sheet metal door having a knob for operating bolts positioned upon the .rear side ot the door; the position orf the `lock upon the rear face of the door is indicated by dotted lines, the several parts being shown in their locked position;

Fig. 2 is a rear view oi the device shown in Fig. 1, showing the elements in their locked position;

Fig. 3 is a view similar to Fig. but

showing` the parts in their unlocked position;

Fig. 4 is an enlarged view oil a portion ot the locking mechanism shown in Fig. 2; F ig. 5 is an enlarged view ot a portion of the locking mechanism shown in Fig.

i cylinder lock.

l have shown my improved device applied to a sheet metal door designated as .10,the marginal portion oit the inner face of which is shown contacting with a portion ot the door frame 11. The outer tace oi the door is provided with a knob 12 rotatably mounted in the same, Upon the rear face of the door 1() provided a swinging bolt 13, which is rigidly secured to a portion ot the knob 12 which extends through the door. The swinging bolt is preferably spaced from the door 10 by a washer or similar means 13. The bolt 13 is so positioned upon the door that when an extension 14 formed upon this bolt is swung to a horizontal position, this extension will lie back of and in locking engagement with a portion of the door frame 11, as is shown in Figs. 1, 2 and 6. In order. to prevent the extension 111 from being swung past the proper locking position, a stock such asthe pin 15 may` be rigidly secured to the door 10.

In addition to the locking means 1.41- just described, it is often advisable to provide sheet n'ie'tal doors with locking means for both the top and bottom of the saine, it being` obvious that itt the sheet metal door is ina-dc of very thin metal and the door is rather long, it would not be ditlicult to spring either end of the door away from the door trame while the middle of the door may remain in its locked position. ln order to provide means :tor locking the door at both its top and bottoni, l provide the sliding bolts 16 having their inner ends pivotally mounted upon the bolt 13 by means of pins or similar means 17 at points diainetrically opposite each other and at substantially right angles to the locking means 1li, so that the bolt member 13 forms actuating means for the bolts 16.

From the structure so fait described, it will be seen that all three of the locking means above mentioned; that is, the locking means 141 and the bolts 16 for locking` the door at the top and bottom of the same, may be operated simultaneously by rotating the knob 12. This simultaneous operation is clearly shown in Figs. 2 and 3 ot the drawing.

In order to secure the locking` bolts above described in their locked position, I pro vide preferably a cylinder lock 18, altl'iough it will be apparent that'my invention is not necessarily limited to this particular type ol lock. rIlhis lock 18 is secured to the rear tace of the door 10, and is preferably positioned adjacent one ot the slidin bolts .LG and near the pivote-d end ot the same. liowever, it will be seen that this is not the only position which the lock may be given in order to hold the bolts above referred to in their ylocked position. The door 10 is provided with a round opening in which the vescutcheon 19 of the cylinder lock may be positioned. Adjacent the escutcheon and formed integral upon the caso of the cylinder lock are provided a pair oit oppositely projectii'ig` lugs .2O havingdrill holes the-rein Q1, adapted to receive rivets or the like by means oiE which the lock may be firmly secured to the rear i'ace olf the door l0. The cylinder lock is provided with the usual pin tumbler extension i2, provided with the well-known pin tumblers 23. rllhe cylinder lock'is further provided with a key-plug or barrel 2li, which barrel preferably provided with a rearwardly projecting end portion, which end portion has loosely mounted upon. the same a swinging bolt designated inits entirety by the numeral Q5. This bolt is rei`era.bly provided with an enlarged rim-like portion 9,6 tormed at one' end thereoi'r', having a round hole Q7 therein which receives the projecting end ot the key-plug'. Upon one tace ot the ring-like portion QG is formed a lue 28, and upon the opposite tace ot the ringlike portion is a second lug or projection 29. The ringdike portion 26 is Yfurther 'Ifiroyided with the extension 30. which lies in a plane extending radially to the portion 26 but forms an angle with the tace of the portion Q6, so that when the bolt is mounted upon the rear end ot the lrey barrel, the outer end 30 inelines towards the tace ot' the door upon which the lock is n'iounted, the arrangement being such that the outer end oi'' the swingA ing;` bolt will lie back ot one oif the rods 1G when the bolt is swung` to its lockingv position, as shown in Fig-s. 2 and o. It will. be apparent trom the above description that when the swinging bolt is moved into loe-hin` engagement with one ot the bolts 1G, both. ot the bolts 16 and the locking;` means 14 will be locked in their protracted posh tion. 'The swinging bolt is preferably secured upon the rearwardly projecting' endr of the key-plug 24rby oppositely projecting` pins rigidly mounted in the rear end of the key-plug 2li. rIhese pins serve not only as means for retaining` the bolt Q5 upon the extension. but also provide a lazy connection between the extension and the swinging' bolt, the extension upon the liey-plug will not move the swinging bolt until one or the other ot the pins 31 is brought into contact with the lug` :28. When one olf the pins 31 is brought into engagement with the lug 28, the swinging bolt may then `be rotated until either the projection 29 or a face of the eX- tension 80 is brought into Contact with the key tumbler extension The object in providing the lazy connection between 'the key-plug andthe swinging` bolt is to permit the key to be removed trom the` lool; when the swingingbolt 25 is in either its locking or idle position. Since in the type of loclr herein disclosed the key cannot be removed from or inserted in its hey barrel except when the same is in the position shown in Fie'. 7, the lazy connection between the key barrel and the siy'iiigiiigl bolt 25 is provided to permit the hey barrel to be given a coinplete rotation in order that the `lzey may be withdrawn.l without swinging the bolt through a complete revolution and into locking' position again.

From the above description it will Abe seen that I have provided a simple, desirable and eiiicient means for locking` the bolts upon the inner side ot a` door in their protracted position. rlhe lockingmeans which I preyide is entirely separate and independent trom the knob-operated bolts. so that my locking device may easily be applied to a door without reoniiringi` any altera-tion in the lmob-eontrolled bolts with `which the door may previously have been provided.

lfilhile I have described the knob-operated bolts and the locking' means t'or the same as applied to a sheet metal door. it is apparent that this structure may be used upon other doors and that my locking; means may be used 'for other purposes.

Various changes may be .made in the details oi the construction without departinu from the'seope of the invention as defined in the claims.4
